GEORGE E. KINZEL, OF WEST ORANGE, NEW JERSEY.

WINDOW-LOCK.

Specification of Letters Patent.

Patented Nov. 11, 1919..

.Application filed May 21, 1919. Serial No. 298,734.

To all whom it may concern.

Be it known that I, GEORGE F. KINZEL, citizen of the United States of America, residing at WVest Orange, in the county of Essex and State of New Jersey, have invented new and useful Improvements in lVindow-Locks, of which the following is a specification.

The object of the invention is to provide a simple, inexpensive and etficient double sash lock, capable of holding both upper and lower sashes in their closed position and adapted to be applied to the ordinary window sashes with a minimum of structural alterations or modification thereof, and hence adapted to be applied without the employment of skilled labor; and to this end the invention consists in the construction, combination and relation of parts of which a preferred embodiment is illustrated in the drawing, it being understood that changes in form and proportions may be resorted to within the scope of the appended claims without departing from the principles involved.

In the drawings:

Figure 1 is a face view of the lock applied in the operative position to a window.

Fig. 2 is a vertical sectional view of the same.

Fig. 8 is a plan view of the socket'plate which is employed in connection with the meeting rail of the lower sash.

Fig. 1 is a perspective view of the mounting or bearing plate adapted for attachment to a side rail of the upper sash. V

The lock embodying the invention consists essentially of a pivotally mounted bolt 10 adapted to be supported by a side rail of the upper sash indicated at 11, and designed when in looking position to be disposed in a downwardly and inwardly inclined relation to the plane of the sash for terminal engagement with a socket 12 formed in the upper side of the meeting rail of the lower sash, such socket being protected by a socket plate 13 secured to the surface of the meeting rail and provided with an opening it into which the extremity of the bolt projects.

The mounting of the bolt upon the upper sash may be efi'ectively accomplished by means of a bearing plate 15 provided at an intermediate point with an offset cylindrical bearing sleeve 16 preferably formed by bending the plate as shown to. receive the spindle 17 which is formed upon and transverse to the bolt 10 and is held yieldingly in position to maintain the bolt in engagement with one of the seats 18 and 19 at the end of the opening 20 in said sleeve, by means of a coiled spring 21. The seats 18 and 19 form continuations or extensions of the opening 20 representing a cutaway portion of the sleeve 16 to permit of the swinging move ment of the bolt 10, and said seats are separated by a tongue 22 which acts as a stop to prevent swinging movement of the tongue when seated and necessitating the transverse movement of the bolt, or movement thereof parallel with the axis of the spindle 17, in order to transfer the bolt from one seat to the other and thus hold the latter either in the looking or disengaged position as indicated respectively in full and dotted lines in Fig. 2.

When as indicated, and preferred, the sleeve 16 is of a diameter considerably exceeding that of the spindle 17 of the bolt, the portion of the sleeve to one'side of the opening 20 may be provided with a filler 23 in which is constructed a bearing 24: corresponding in diameter with said spindle and serving as a seat for the spring 21.

It will be understood that the treatment of the window sashes required in order to adapt the fastener thereto, consists is providing the socket 12 in the meeting rail of the lower sash and which is covered by the socket plate 18, the opening 14 of said plate being of a suiiicient length to permit of the lateral movement of the bolt under the influence of the spring 21 after the terminal of said bolt has been depressed into engagement with the opening. Obviously to release the sashes it is only necessary to repress the bolt against the tension of the spring until it is released from the tongue 22 whereupon said bolt may be elevated and secured in the inoperative position indicated in dotted lines in Fig. 2.

Claimed 1. A sash lock having a bearing sleeve and means for attaching the same to an upper window sash, a pivotal bolt having a spindle mounted for axial movement in said bearing, said bolt being adapted to occupy a downwardly and inwardly inclined position in terminal engagement with the meeting rail of the lower window sash, seats within the range of pivotal movement of said bolt for the reception thereof respectively in its locking and disengaged positions, and yield- I 5 attachment to the upper sash and provided with a bearing sleeve having a guide openlng, a' swlnglng vbolt having a transverse spindle mounted for axial movement in said bearing sleeve, the bolt being arranged to 10 project through the guide opening for downward and inward inclination and terminal engagement with a socket on the meeting rail of the lower sash, said guide opening having extensions forming spaced bolt seats, and a spring for impelling the bolt spindle 1- axially t0 yieldingly maintain the bolt in en agement with one of said seats.

11 testimony whereof I afliX my signature.

GEORGE F. KINZEL.
